Lucky you, Peter! Here's the report from SpaceWeather.com:
POWERFUL GEOSTORM: A powerful geomagnetic storm raged for nearly
15 hours after a pair of coronal mass ejections swept past our planet
around 0530 UT on Saturday, Nov. 24th. In the United States sky watchers
reported auroras as far south as Arkansas. Observers in Australia have
also spotted auroras -- so this storm has triggered Southern Lights
as well! [photo gallery]

Geomagnetic disturbances are subsiding. Nevertheless, the solar wind
speed remains very high. If the interplanetary magnetic field near
Earth tilts south, auroral activity could intensify again. Sky watchers
located at magnetic latitudes greater than ~55 degrees should remain
alert for auroras after nightfall -- and especially around local
midnight.
